Poetry doesn't fully add some packages (PyQt5, Jupyter)

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: macOS High Sierra 10.13.5
• Poetry version: 0.11.2

Issue

I have to pip install pyqt5 to get pyqt5-sip

Now it works.

About Jupyter Notebook, even though it seems not completely installed, I can use it without problems.

PyQt seem to have fixed the issue with their metadata version, but poetry still fails to install pyqt5-qt and pyqt5-sip.

The metadata now:

Metadata-Version: 2.1
Name: PyQt5
Version: 5.15.6
Requires-Python: >=3.6
Summary: Python bindings for the Qt cross platform application toolkit
Home-Page: https://www.riverbankcomputing.com/software/pyqt/
Author: Riverbank Computing Limited
Author-Email: [e-mail]
License: GPL v3
Requires-Dist: PyQt5-sip (>=12.8, <13)
Requires-Dist: PyQt5-Qt5 (>=5.15.2)

Installing with pip successfully installs pyqt5-sip and pyqt5-qt5, and pyqt5 no longer errors trying to find Qt libraries. Could this be an issue with poetry?

I can confirm that doing poetry add pyqt5-sip pyqt5-qt5 resolves the issue, for anyone coming across this page, but obviously it would be better to not have to specify these manually.

I just bumped into this bug when migrating to poetry. It looks like Poetry is still failing to install PyQt5-Qt5 even though the metadata file appears to be correct now (as far as I can tell).

@sdispater Can we re-open this ticket, or should I make a new one?
